Altite No Chrome Metal Finishing Technologies

A metal finishing conversion coating, etching, and primer technology that does not use chromates and was demonstrated on a small scale

The US Navy has developed a suite of completely chrome-free primers, etches, and conversion coatings that offer excellent corrosion protection and superior bonding strength in economical, drop-in formulations.

The Naval Undersea Warfare Center Division Newport has developed, tested, and patented Altite, a suite of technologies that use titanates in a drop-in process to replace hexavalent chromium commonly used to prevent corrosion on metals. The process also eliminates the need for ferro-cyanide in the bath, further reducing toxic elements and waste streams. Altite offers superior bonding performance compared to chromated products, especially in bonding titanium to carbon fiber composites.

Altite meets a variety of MIL-SPECS, including MIL-A-8625F for aluminum and aluminum alloys, and MIL-C-5541E for conversion coatings on aluminum. Product and application costs are competitive with existing processes. Personnel exposure concerns are vastly reduced compared to chromated products.
